PATENT CHEMICAL FIRE-ENGINE.

SPECIFICATION forming part of Letters Patent No. 313,755, dated March 10, 1885.

(No model.)

To all whom it may concern.-

Be it known that I, WILLIAM MORRISON, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, haveinvcnted certain new and useful Improvements in Chemical Fire-Engines, of which the following is a specification.

The object of the invention is to devise a chemical fire-engine in which a constant stream of equal volume can be ejected; and it consists, essentially, in locating below a water tank or reservoir a cylinder divided into two chambers and carried horizontally in journals, upon which it may be revolved, a discharge pipe passing through each journal into the respective chambers formed at either end of the cylinder, the two discharge-pipes thus leading into the chambers of the cylinder being connected to a discharge-pipe common to both, and to which the hose is attached, suitable valves being provided so that one dischargepipe may be cut off while the other is open to communicate with the discharge-pipe common to both, suitable appliances being provided by which the water from the elevated tank or reservoir may be readily discharged into the respective chambers within the cylinder, substantially as hereinafter moreparticularly eX-.

plained.

Figure 1 is a side elevation of myimproved chemical fire-extinguisher. Fig. 2 is a sectional view of the horizontal cylinder. Fig. 3 is an end view ofcylinder and rechargingtank.

A is the water tank or reservoir, suitably supported by the frame of the machine and located above the cylinder B.

C are trunnions journaled in suitable bearings supported by the main frame of the machine, and located, as indicated, at opposite ends of the cylinder, which they are designed to support, the trunnions forming the pivotpoint upon which the cylinder B may be revolved. These trunnions'are, it will be noticed by Fig. 2, hollow to permit the, discharge-pipes D to pass through them, suitable stuffingboxes being provided to prevent the escape of the gas through the joint formed between the discharge pipes and trunnions. While the cylinder may be revolved, the dis charge-pipes D remain stationary in the position they are shown in Fig. 2. As the inner the cylinder B. At this point the dischargepipe E is connected, and is therefore common to both the discharge-pipesD.

F are cutoff valves, located on opposite sides of the discharge-pipe E, and designed to cut off the discharge-pipe D, leading from one end of the cylinder, while the disehargepipe from the other end of the cylinder is open. In order to permit this end to be accomplished quickly and efficiently from either end of the cylinder, Iprovide two horizontal rods, G and H, supported from the discharge-pipes D by the pivoted links I. Consequently, the longitudinal movement of either of the rods G and H will cause the one moved to be carried closer to or farther from the discharge-pipe D), and, consequently, by connecting the spindles of the cut-off valves F, they are opened or closed by the longitudinal movement of the horizontal rod to which they are respectively connected.

As shown in Fig. 1, the horizontal rod G is located so as to hold open the cutoff valve F on the left-hand side of the discharge-pipe E, while the horizontal rod H is located so as to close the cutoff valve F, to which it is attached, and which in the figure referred to is located on the righthand side of the dischargepipc E.

As shown in the drawings, the dischargepipe E leads into the axle of the hose-reel J, which axle is hollow, and is provided with a discharge-connection, to which the hose is attached. Although I consider this a preferable plan of arranging the discharge-pipe IE, it will of course be understood that the hose-reel J may be dispensed with without affecting the general arrangement of my invention.

Having now described the general construction of my improved chemical fire-engine, I shall proceed to explain, briefly, its opera tion; but before doing so, I may mention that a chemical fire-engine not provided with a water-reservoir located above the cylinder must, where water-pressure is not attainable, I quently it is not possible when the "pipe K is have its cylinder filled by buckets, which process is so slow that although there may be two cylinders connected with the common discharge, it necessarily takes longer to fill the empty cylinder than it does to empty the full By the adoption of my peculiarly-arranged cylinder and water-reservoir, which latter ought more properly to be called a recharging-tank, the above-mentioned difficulties are avoided.

On reference to Fig. 1 it will be noticed that there are two pipes (marked K) extending from opposite sides of the rechargingtank. or reservoir A. These pipes are provided with suitable out off valves, as k, (shown in dotted lines,) so that the fiow of water from the tank may be stopped or regulated, as circumstances require. These pipes K extend, respectively, to a point over the cylinder that will permit the opening in the cylinder made for theinsertion of the acid-pot L, or any other 5 suitable opening, to be brought below it in order to permit the water from the recharging-tank A to be discharged through the pipe K, to which a flexible nozzle is attached, into one or other of the chambers at the opposite hand side of Fig. 1.

- ually cuts oft the discharge-pipe E from the interior of the chamber on the right-hand side of the figure, which chamber is supposed at the time to require recharging. The operator, immediately upon arranging the valves as specified, removes the acid-pot L belo'nging to this particular chamber. The hole in the cylinder thus left is then brought below the pipe K, when the valve in the pipe K is opened and the water from the reservoir or recharging-tank A is permitted to flow into thechamber at the right-hand end of the cylinder. As soon as suificient water is thus permitted to flow into the cylinder, the cut-off valve from the pipe K is closed, and the acidpot L replaced and screwed once more into position, whenthe chamber thus recharged is ready for use.

By pivoting the cylinder B on the trunnions O, as hereinbefore referred to, the said cylinder can readily be adjusted not only to bring it properly below the pipe K, but also to move it intoa position where the operator can readily take out or replace the acid-pot L.

By placing the pipes K at points on one or the other side of the tank A the hole in the cylinder must necessarily be on a slight incline when brought beneath the said pipe K, which angle permits the water to flow out of the hole before the cylinder is completely full; conse thus arranged for the operator to put too much water into the cylinder.

\Vhat I claim as ,my invention is 1. In a chemical fire-engine in which the re- I chargingtank or water-reservoir is located above the cylinder, the hollow trunnion O, fixed to either end of the divided cylinder B, and arranged to support ithorizontally, in combination with the discharge-pipe D, passing through the trunnions into the chambers at either end of the cylinder, and connected at their outer ends to a discharge-pipe common to both.

2. In a chemical fire-engine in whicha recharging-tank or water-reservoir is located above the cylinder, the hollow trunnionC, fixed to each end of the divided cylinder B, and fitting into bearings formed on the main frame of the machine, so that the said cylinder may be revolved on the bearings with the trunnions as pivot-points, holes being made in the side of the'cylinder leading into each chamber, and designed to hold the acid-pots tion of a horizontal cylinder divided into two chambers and pivoted in suitable bearings formed in the frame and arranged to support hollow. trunnions fixed to the ends of the cylin- ICO der, the discharge-pipes D, extending through the hollow trunnions 0 into the chambers formed within the cylinder to a point near the bottom side-of the said cylinder, with a discharge-pipe, E, common to both dischargepipes D, and provided with asuitable outlet, to which a hose or pipe may be connected for the purpose of forming the discharge-pipe D into siphons, substantially as and for the purpose specified.
